Hi everyone for this problem. It reads what type of reaction occurs between copper and silver nitrate. So let's go ahead and start off by writing this out. We have copper plus silver nitrate and we want to know what type of reaction this is. So let's identify what is here. We have copper which is a metal. And we have silver which is also a metal. Okay, And let's go ahead and label these as a B. And see. Okay, so we have because we have two medals here, we're going to look at the activity series table because we need to look at the reactivity of the elements involved here. Okay, so our activity series table tells us our most reactive to our least reactive. And when we look at the activity series table, we see that copper is higher than silver. So that means copper is going to be more reactive than silver. And more reactive elements will replace less reactive elements in a single replacement reaction. Okay. And so what this looks like then, is our copper is going to replace the silver here. And so when we rewrite this out, we're going to get copper and our nitrate plus our silver. Okay, so this type of reaction we said is a single replacement reaction. And all single replacement reactions are also redox oxidation reactions as well. So, our answer for this problem is that the type of reaction is a redox reaction. Okay, so this is going to be our final answer and that is it for this problem. I hope this was helpful
